[IronPython] Using Wing IDE with IronPython - autocomplete for .NET objects (PI file generator)

This sounds great. I am new to both IronPython, WingIDE and Windows
development in general.
One of the disappointing things with WingIDE for me is the total absence
of autocompletion of .NET imports and also the DLL Assembly References
I've added to access the libraries my app requires.
Unfortunately, for most of what I would like, I believe it would require
WingIDE to support the use of IronPython. Is this accurate? And if
WingIDE did support the use of IronPython would it make what you are
doing easier or possibly unnecessary?
I am exploring my IDE options. So I am somewhat disappointed with
WingIDE not providing autocompletion or any of the features for which I
am explicitly needing to use IronPython for. Unfortunately I really
haven't found anything that does provide autocompletion for the
libraries I've imported via clr. Oh well. It is possible I've missed
I would love to see WingIDE support IronPython and enabling
autocompletion, debugging, etc. on .NET and clr imported libraries and
Thanks for doing this Michael. It will be a nice help. And also thanks
for your book which I am working my way through.
